Application filed August 1, 1912. Serial No. 712,631.

row or be inoperative, as desired; the object of my invention being to provide a harrow simple and strong in construction and readily adjustable from'an operative position to one for transportation. These objects are attained by means of mechanism, one embodiment of which is illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a harrow having my invention embodied in its construction; Fig. 2 is a detached detail on an enlarged scale showing part of the front turnable tooth carrying bar and the manner of mounting the transport wheel thereon; Fig. 3 is a detached detail on an enlarged scale showing part of the rear turnable tooth carrying bar and the manner of mounting the carrying wheels thereon; the parts being shown in inverted position to facilitate clearness of illustration; Fig. 4 is a side elevation of Fig. 3, the parts being in the inverted position shown therein; Fig. 5 is a side elevation of Fig. 2; Fig. 6 is a longitudinal sectional elevation of Fig. 1 along line AB and showing the harrow in an inoperative and the carrying wheels in an operative position; and Fig. 7 is a similar elevation as Fig. (i and illustrating the harrow in an operative position with the carrying wheels raised from the ground.

The same reference characters designate like parts throughout the several views.

The frame of the harrow includes a .U- shaped member having a transverse head portion 1, and longitudinally arranged side members 2, to which brackets Sare secured,

having bearings 4 at the upper ends thereof.

in which are journaled opposite ends of turnable tooth carrying bars 5 having arms 6 secured to the middle portion thereof,

and 7 represents a bar pivotally connected with the arms.

8 represents a toothed sector secured to the rear end of the bar 7 and cooperating with a hand lever 9 pivotally connected with saidbar andsecured to one of the arms 6 1n a manner to retain the turnable tooth carrying bars 5 in any position desired, and 10- represents spring teeth secured to the turnable bars.

11 represents a bOX-likdblflCkGt member having a saddle portion 12 that receives the middle portion ofthe front tooth car.-

rying bar, to which the bracket is secured by means of abolt 13.

141 represents forwardly extending arms having the rear ends thereof secured to the bracket, "and 15 represents a carrying wheel journaled between opposite ends of arms.

16 represents transversely spaced bracket members secured to the rear tooth carrying bar and. provided with outstanding ear members- 17. To each set of these ears 17 is pivotally connected one end of wheel carrying arms 18 having a. carrying wheel 19 journaled between opposite ends thereof.

said

'20 represents a U-shaped sliding detent' carried by the bracketmembers 16, having a compression spring 21 encircling one of the legs'thereof and 013611113116 between a pin 22 and one of the ear members 17 in a manner to yieldingly press the detent in a direction to cause the opposite leg to engage with one of the bars 18 and an opening in one of the ears in a manner to lock the bars against a swinging movement when the harrow teeth are in operative position and the wheel carriers are turned upward and rearward, as shown in Fig. 7

The operation of the mechanism will now be described.

"With the parts in the position shown in Fig. 6, wherein the tillage members 10 are in their inoperative position and the wheels 15 and 19 engage the ground, when the operator desires to throw the tillage members into engagement with the ground, he throws the lever 9 to the left. Through the bar 7 and arms 6, the tooth-carrying bars 5 are thus rotated in a counter-clockwise direction in such a manner as to lower the teeth 10. As this movement continues, the front wheel 15, through its connection to the front arms 6, will obviously be raised upward and forward toward the position shown in Fig. 7,-and the rear wheels 19 will be thrown forward and beneath theframe until they occupy a position in frontofthe rear bar 5,

W h their arms 18 in a position substan=-- tiallyat right angles to the position shown in Fig. 6 and thei'r-rimsresting upon the ground. When in this position the operator may then readily raise the wheels 19 to theposition shown in Fig. 7 and lock them in that position by the detent 20. With the parts occupying the position shown ,in Fig.

7, when the operator wishesto' raise the im plements 10 outof the-ground and prepare the machine fortransport, he swings thel ever 9 to theright. During this movement the wheel will obviouslymove downward from the position shown in Fig.1?- toward the position shown in' Fig. 6 and the wheels tormay obviously. disconnect the wheels 19 by releasing the detent mechanism- 20,

l the frame. to their transport position.

whereupon the wheels will drop upon the ground in such a position that as the harrow moves forward, they will be pulled back under the rear end of the frame until they occupy the position shown in Fig. 6.

In this construction it is to be noted that when desired the operator, during trans port, mayuseonly the-wheel '15, the rear end of the lower frame 2 then dragging upon the ground. Wh.en,'however, it is desired to raise the rear end of" the frame to the position shown in Fig. 6 after the op erator has moved the wheel 15 to its trans port. position, he may readily throw the wheels 19 to their transport position by simply disconnecting the detent 20, the forward movement of the machine acting to swing the wheels backward and underneaph n fact, byfthis construction it is to be noted that the operator is not required to lift the harrow at all, but only to throw the front wheel 15 down into. contact with the ground,

release the detent mechanism 20 so that the wheels 19 rest upon the ground, and then 'hold th'evsector, detent released" as the team moves forward, whereupon the forward movement of the wheels over the ground turns these wheels into their operative po-' sitions shown in Fig. 6. -Attention' is also directed to the fact that by means of the detent mechanism, the wheels 19, when in their inoperative position,

against a'swinging movement with respect to the frame, Further, when in. their operative position,-it.is to be noted that due to the fact that their arms 18 then underlie the rear bar 5 and engage therewith, a substantial frame support is provided.

" While Ihave in this application specificallydescribed onejembodiment of my in-:

vention, it' is, of course, to be understood are securely held fixed thereto, a transport wheel, a forwardly protruding bracket rotatable with said bar, and a rigid draft connection for said transport wheel pivotally connected to said bracket at'a point in front of said bar and extending rearwardly therefrom beneath the latter.

2, Ina tillage implement, a frame, implements carried thereon, transport wheels carried thereon, manually operated means for moving one of said elements toward operative position as the other is moved toward inoperative position, and means operable independently of said first mentioned means and after a predetermined movement thereof whereby upon a forward movement of the frame the movement of one of said elements is automatically completed.
